Herb Gross introduces Linear Relationships, the building blocks for more complex problems. The meaning of a linear relationship between input and output is: "When the input increases by 1 unit, the output changes by a fixed amount." The picture (graph) of a linear relationship is a straight line - hence its name! Then watch Herb match examples to the linear pattern y = mx + b. Herb Gross describes the benefits of self-paced learning of Algebra and stresses the relevance of the topics that are covered in this course.
